Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a water treatment agent spraying and mixing equipment. Background Technology

[0002] In industrial and municipal water treatment processes, it is often necessary to add chemical agents to sewage and wastewater treatment tanks. Common methods of adding these agents include fixed spraying or simple pipeline injection.

[0003] The nozzle height of the fixed spray pipe is not adjustable, and its installation position is determined according to the liquid level under the design conditions. However, in actual operation, the water level in the treatment tank will frequently rise and fall due to fluctuations in the influent flow rate and changes in the production cycle. When the liquid level is much lower than the nozzle, it will cause chemical splashing and aerosol diffusion, resulting in chemical waste and environmental pollution, while also affecting its mixing effect. When the liquid level is too high, the nozzle is submerged below the liquid surface, which prevents the liquid above from being sprayed with chemicals, resulting in problems such as local over-dosing of chemicals and uneven mixing. Utility Model Content

[0004] The purpose of this invention is to provide a water treatment agent spraying and mixing equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water treatment agent spraying and mixing equipment, comprising a treatment tank, wherein an inlet is provided at the upper end and an outlet is provided at the lower end on both sides of the treatment tank, and a plurality of drain pipes are provided inside the treatment tank, adjacent drain pipes being connected by branch pipes, and a plurality of nozzles are provided at equal intervals on the branch pipes, the nozzles being used to spray agents into the treatment tank; both ends of the drain pipes are provided with adjustment units, each adjustment unit comprising a fixed frame and a sliding seat, the fixed frame being fixedly connected to the inner wall of the treatment tank, the sliding seat being slidably disposed in the fixed frame, and both ends of the drain pipes being fixedly connected to two corresponding sliding seats respectively; the uppermost sliding seat is connected to a tensioning unit, which drives the sliding seat to move within the fixed frame.

[0006] Preferably, the processing box is equipped with a connecting frame, and a main pipe is installed in the connecting frame. One end of the main pipe is connected to the uppermost drain pipe, and the main pipe is connected to an external medicine tank through a pump.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-4 The water treatment agent spraying and mixing spraying equipment shown includes a treatment tank 1. The treatment tank 1 has an inlet 11 at the upper end and an outlet 12 at the lower end on both sides. The treatment tank 1 is provided with a number of drain pipes 51. Adjacent drain pipes 51 are connected by branch pipes 52. Multiple nozzles 53 are opened at equal intervals on the branch pipes 52. The nozzles 53 are used to spray agents into the treatment tank 1.

[0022] When the water level in the treatment tank 1 is H, the spray height of the uppermost drain pipe 51 should be adjusted to the range of H-0.3m to H-0.5m to ensure that the agent is sprayed in a parabolic manner. The lower drain pipes 51 are distributed at equal intervals, with a recommended interval of 0.5m to 0.8m.

[0023] The water level height H refers to the vertical distance from the bottom wall of the treatment tank 1 to the liquid surface, which is monitored in real time by a liquid level sensor.

[0024] A baffle plate is installed on the inside of the inlet 11 to make the water flow in an S-shaped path and prolong the residence time;

[0025] The nozzles 53 of the drain pipe 51 adopt a fan-shaped spray angle, and the spacing between the nozzles 53 is no more than 0.3m to ensure coverage.

[0026] Both ends of the drain pipe 51 are provided with adjustment units 3. The adjustment unit 3 includes a fixed frame 31 and a sliding seat 32. The fixed frame 31 is fixedly connected to the inner wall of the processing box 1. The sliding seat 32 is slidably disposed in the fixed frame 31. Both ends of the drain pipe 51 are fixedly connected to two corresponding sliding seats 32 respectively. The uppermost sliding seat 32 is connected to a tensioning unit, which drives the sliding seat 32 to move in the fixed frame 31.

[0027] The contact surface between the sliding seat 32 and the fixed frame 31 is embedded with a polytetrafluoroethylene wear-resistant bushing, and a rubber sealing ring is provided in the sliding gap to prevent sewage from entering; the inner wall of the fixed frame 31 is coated with an anti-corrosion coating (such as epoxy resin).

[0028] The drain pipe 51 and nozzle 53 are made of 316L stainless steel or polyvinyl chloride, which are resistant to chemical corrosion.

[0029] Branch pipe 52 is connected to drain pipe 51 via a flange to ensure a tight seal.

[0030] The stretching unit drives the sliding seat 32 to move in the fixed frame 31 to drive the drain pipe 51 to move synchronously, thereby adjusting the spray height of the drain pipe 51 in the treatment tank 1; the spray height can be adjusted according to the water level in the treatment tank 1 to adapt to different wastewater levels and realize the rapid mixing of the reagent and wastewater.

[0031] Compared to the shortcomings of fixed spray pipes in the prior art, the height adjustment of the drain pipe 51 increases the coverage of the sprayed agent and reduces the mixing dead zone.

[0032] The sliding seat 32 slides within the fixed frame 31, causing the drain pipe 51 to move accordingly. This adjusts the height of the drain pipe 51, thereby adjusting the spray height of the drain pipe 51 within the treatment tank 1. The height of the drain pipe 51 can be adjusted according to the water level in the treatment tank 1, thus adjusting the spray height of the drain pipe 51. This facilitates spraying wastewater at different heights within the treatment tank 1, enabling rapid mixing of the reagent and wastewater.

[0033] The height of the drain pipe 51 and nozzle 53 is adjusted by the adjustment unit 3 and the tensioning unit. According to the real-time liquid level in the treatment tank 1, the operator adjusts multiple drain pipes 51 to the optimal spraying height, so that the agent is sprayed into the water at a height, which enhances the mixing degree of the agent and water and avoids the mixing dead zone. At the same time, some drain pipes 51 are distributed in the liquid for injection spraying, so as to evenly disperse the agent and quickly mix it with the wastewater.

[0034] A connecting frame 2 is installed on the treatment box 1, and a main pipe 5 is installed in the connecting frame 2. One end of the main pipe 5 is connected to the uppermost drain pipe 51, and the main pipe 5 is connected to an external medicine tank through a pump.

[0035] The agent in the agent tank is pumped to the main pipe 5, and the agent is delivered to multiple drain pipes 51 through the branch pipe 52. The agent is sprayed at different liquid levels in the treatment tank 1 through the nozzle 53 to facilitate rapid mixing.

[0036] Example 1: The bottom sliding seat 32 is fixedly connected to the fixed frame 31, and the other sliding seats 32 are slidably connected to the inner wall of the fixed frame 31. The bottom sliding seat 32 does not participate in height adjustment and only serves as a support.

[0037] Since it is slidably connected to the inner wall of the fixed frame 31 with the sliding seat 32, the vertical sliding of the sliding seat 32 is limited, thus limiting its sliding path.

[0038] The adjustment unit 3 also includes a rotating rod 33 and a connecting seat 34. One end of the rotating rod 33 is rotatably connected to the sliding seat 32 via a hinge shaft, and the other end of the rotating rod 33 is rotatably connected to the connecting seat 34 via a hinge shaft. The rotating rods 33 between adjacent sliding seats 32 are hinged together via the connecting seat 34, and a telescopic rod 35 is fixedly connected between adjacent connecting seats 34.

[0039] One end of the rotating rod 33 is rotatably connected to the sliding seat 32, and the other end of the rotating rod 33 is rotatably connected to the connecting seat 34. As the connecting seat 34 moves, the two connecting seats 34 drive the two rotating rods 33 rotatably connected to them to move accordingly. At the same time, since the end of the rotating rod 33 away from the connecting seat 34 is rotatably connected to the corresponding sliding seat 32, and the sliding path of the sliding seat 32 is limited, the rotation angle of the rotating rod 33 is limited. Under the same rotation of multiple rotating rods 33, the distance between adjacent sliding seats 32 is limited to be the same. The movement of the sliding seat 32 limits the movement of the drain pipe 51 installed between the sliding seats 32, ensuring that the distance between adjacent drain pipes 51 is the same.

[0040] Adjacent rotating rods 33 are connected by a universal coupling, allowing for slight deflection to compensate for installation errors.

[0041] When the topmost sliding seat 32 moves, it drives the rotating rod 33 to rotate, which in turn drives the adjacent sliding seats 32 to move synchronously through the connecting seat 34, so as to realize the linkage adjustment of the height of all drain pipes 51; the telescopic rod 35 is used to keep multiple connecting seats 34 at the same vertical height, and can adaptively adjust the spacing between adjacent connecting seats 34 according to the rotation angle of the rotating rod 33.

[0042] When the topmost sliding seat 32 moves via the pull rod 4, the rotating rod 33 rotates around the hinge axis. The rotation angle is proportional to the displacement of the sliding seat 32. The motion is transmitted through the connecting seat 34, so that the adjacent sliding seats 32 move synchronously. The displacement difference is compensated by the telescopic rod 35. The linkage mechanism is based on the parallelogram principle to ensure that the spacing of all drain pipes 51 is consistent.

[0043] Example 2: The tensioning unit includes a pull rod 4 and a pulling frame 41. The bottom end of the pulling frame 41 is fixedly connected to two uppermost sliding seats 32, and the pull rod 4 is fixedly connected to the top end of the pulling frame 41.

[0044] By pulling the lever 4, the pulling frame 41 is moved, thereby adjusting the height of the top sliding seat 32, which in turn adjusts the height of the drain pipe 51 between the two sliding seats 32. In conjunction with the rotating rod 33, the height of the adjacent drain pipes 51 is adjusted, so that the multiple drain pipes 51 are distributed at a suitable liquid height, which facilitates the spraying and mixing of the agent.

[0045] The tensioning unit can be equipped with a drive device, which can be a cylinder or an electric push rod. The cylinder or electric push rod is connected to the pull rod 4 and is connected to the liquid level sensor signal through a controller for automatically adjusting the lifting and lowering of the pull rod 4.

[0046] A fixing seat 42 is fixed on the connecting frame 2, and the pull rod 4 is slidably disposed in the fixing seat 42. Bolt holes are provided on the fixing seat 42.

[0047] By installing bolts in the bolt holes, the bolts can be pressed against or separated from the pull rod 4 to control the fixing and sliding of the pull rod 4, thereby adjusting the height of the pull frame 41.

[0048] A movable base 43 is fixedly connected to the top of the lever 4.

[0049] A cylinder or electric push rod can be installed on the connecting frame 2. The cylinder or electric push rod controls the moving seat 43 to drive the pull rod 4 to rise and fall, thereby pulling the pull frame 41 to move and adjust the height of the drain pipe 51.

[0050] A liquid level sensor can be installed on the inner wall of the processing tank 1 to monitor the liquid level in the tank in real time. The liquid level sensor is connected to a controller, such as a PLC or a microcontroller control system, and the monitored liquid level signal is fed back to the controller in real time. The controller compares the received liquid level signal with the preset optimal spray height range and sends a control signal according to the comparison result to automatically start or adjust the extension stroke of the cylinder or electric push rod, thereby driving the pull rod 4 to rise and fall, and finally realizing the automatic and precise adjustment of the spray height of the drain pipe 51.

[0051] The liquid level sensor model can be referenced as ULTRASONIC-LV100. The liquid level sensor will be installed in the middle of the side wall of the treatment tank 1 to detect the water level of the treatment tank 1 in real time and transmit the water level information to the PLC controller. The PLC controller model can be referenced as Siemens S7-1200.

[0052] The PLC uses a preset height parameter library to compare with the real-time water level and then outputs a signal to the electric push rod to drive the pull rod 4 to rise and fall.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
